About the business

Stocking a pond with fingerlings, feeding them and selling the fish. Ponds are where most of the country's fish comes from: of 50.18 lakh tonnes produced in 2023-24, 29.78 lakh tonnes came from closed water bodies. This is the one business in Bangladesh where the government itself measures and publishes how much a pond in your district actually yields. The Department of Fisheries put the national average pond yield at 4.96 tonnes per hectare: 12.72 in Mymensingh, 8.28 in Narsingdi, 7.17 in Jashore, but only 2.01 in Rangamati. The same pond in one district produces six times what it produces in another. The department sorts ponds into four classes: extensive under 1.5 tonnes a hectare, semi-intensive 1.5 to 4, intensive over 4 to 10, and highly intensive above 10. Moving up a class means more fingerlings and much more feed, and more risk with the extra return. Over ninety percent of pond fish is a handful of species: pangas, tilapia, rui, silver carp and mrigal. The money arrives once or twice a year, on harvest day, while the feed bill arrives every day.

What you need to start

Nets, lime and fertiliser, a way to check water depth, and for intensive culture an aerator or water pump.Equipment
Fingerlings and fish feed, the two main costs of the year. The more intensive the pond, the more of both.Starting stock
Trade licence from the union parishad, municipality or city corporation: form Tk 10, licence book Tk 50, standard tax Tk 30, stamp Tk 150-300, licence fee Tk 100-60,000 by trade type. Needed to sell commercially and to access government support.Licence
Fish farmer registration and advisory service from the upazila fisheries office under the Department of Fisheries. Registered farmers appear on the lists for training, fingerlings and technical support. The fee and validity could not be verified here.Licence
Reading oxygen from the colour and smell of the water, tracking weight gain, and knowing when to harvest.Skill
A hatchery or government fish seed farm, a fish feed dealer, an ice plant, and an aratdar or wholesaler to take the fish.Supplier
A pond, owned or leased, with banks solid enough that a flood does not carry the fish away, and preferably clear of heavy tree cover.Workspace

How the work is done

1Ask the upazila fisheries office what ponds in your district actually yield per hectare. What works in Mymensingh does not work in Rangamati, and you need to know that before you start.
2Fix the pond, owned or leased. If leased, put the term and the annual rent in writing; intensive culture does not fit a one-year lease.
3Dry out or net the pond to clear predatory fish, repair the banks and apply lime. Skip this and the money spent on fingerlings goes into the water.
4Choose the species. Pangas is the biggest share of pond fish, then tilapia and rui, because they grow fast and always have a market.
5Buy fingerlings from a government fish seed farm or a hatchery you trust. Cheap, weak fingerlings raise the whole year's feed bill and slow growth.
6Set a feeding routine: how many times a day and how many kilos. Feed is the largest cost in this business, and overfeeding fouls the water and kills fish.
7Watch the water colour and the fish every day. Fish gulping at the surface at dawn means oxygen has crashed, and that has to be dealt with then, not the next morning.
8Net a few fish now and then and weigh them. If weight is not going up, the feed or the water is wrong, and every week of delay costs money.
9Line up the buyer before you harvest: aratdar, wholesaler or market retailer. Looking for a buyer after the fish are out means taking whatever price is offered.
10Harvest in stages rather than all at once. Dumping the whole pond depresses the local price and spikes the ice and transport bill at the same time.
11At the end of each cycle work out total kilos against total cost. If cost per kilo is above the selling price, the next cycle needs a different species or stocking density.

Where it works well

Strong fitGazipur · 6.45 tonnes per hectare with the Dhaka market on the doorstep.
Strong fitJashore · 7.17 tonnes per hectare, and an old hatchery belt so good fingerlings are close by.
Strong fitMymensingh · The Department of Fisheries records 12.72 tonnes per hectare here, the highest in the country, with by far the largest area under highly intensive culture.
Strong fitNarsingdi · 8.28 tonnes per hectare, and close enough to Dhaka for the fish to reach a big market quickly.
PossibleBogura · 4.98 tonnes per hectare, just above the national average, and the north's biggest fish arats are here.
PossibleCumilla · 4.91 tonnes per hectare, and on the Dhaka-Chattogram highway so fish can go either way.
PossibleDinajpur · 4.84 tonnes per hectare over a large pond area, but the big markets are far.
PossibleRajshahi · 4.76 tonnes per hectare with a relatively large share under intensive culture.
PossibleTangail · 5.37 tonnes per hectare across a large area of ponds.
Weak fitChattogram · Only 3.00 tonnes per hectare, with much of the pond area still under extensive methods.
Weak fitCox's Bazar · 2.40 tonnes per hectare; freshwater ponds take second place here to shrimp and brackish-water culture.
Weak fitRangamati · 2.01 tonnes per hectare, the lowest in the country, and hauling fingerlings and feed up the hills eats the margin.

Risks and cautions

HighSpoilage: An overnight kill is the big fear. Heat that crashes the oxygen, overfeeding that fouls the water, or a disease outbreak can float most of the pond in one night, after a whole year's feed has already been paid for. And once the fish are out, without ice the price halves within hours.
HighWorking capital: Money comes once or twice a year, on harvest day, while feed is a daily cost. Start without the whole cycle's feed money in hand and you end up cutting the ration mid-cycle; the fish then stop gaining weight and the money already spent does not come back.
MediumDemand: On harvest day you take the price you are given. When many ponds in one area are drawn at the same time the local arat price falls, and there is no way to hold the stock. The most widely farmed species, pangas and tilapia, are also the cheapest.
MediumDependency: On a leased pond everything depends on the owner's decision. Having to give up the pond before the term ends turns the bank repair and liming into a total loss.
MediumOther: Floods and heavy rain that top the banks let the fish out, and none of it is insured. On low-lying land this happens every few years.
